COlN-OPERATED PCWER OR STRENGTH TESTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 423,702, dated March 18, 1890. Application filed June 14, 1889. Serial No. 314,212. (No model.)

that class of machines in which the striking or kicking power of a person may be determined or registered; and it consists in the novel arrangement and construction of parts, as hereinafter set forth.

In the drawings, Figure 1 is a perspective View of the mechanism embodying my improvement with certain parts broken away to save space, and 2 is a side view of the same.

Similar letters of reference indicate like parts in both figures of the drawings.

- Referringby letter to the drawings, A designates a main shaft, (here shown as having bearings in the hangers a,) which may depend from the casing of the machine, (not shown;) or this shaft may have its ends journaled in the front and rear wall of the casing.

B designates a disk or dial mounted friction -tight on the shaft A adjacent to the front wall a, which has a small opening a in line with a circular row of figures or characters on the face of the dial B.

B is a ratchet-wheel rigidly secured to the shaftA in the rear of the dial, and B is a similar ratchet-wheel, but somewhat smaller in circumference than the wheel B, also rigidly attached to the shaft A near its opposite end. These wheels B B itwill be observed, Fig. 1, have their teeth oppositely arranged.

In the rear of the ratchet-wheel B is a toothed or gear wheel 0, which is loosely mounted on the shaft A, so as to turn independently of the shaft. In order that this wheel 0 maynot turn too freely on the shaft, we provide a friction-bearing, (here shown as a spring 0,) arranged in the collar 0 of the 'wheel 0. Another gear-wheel O is loosely mounted on the shaft A at one side of the ratchet-wheel B. This wheel 0 is smaller than the wheel 0. The relative sizes of these I 61 shaft A alternately in opposite directions, as 6 two wheels is not material, but we prefer the Wheel 0 to be about one-fourth of the size of the wheel 0.

D is a clutch-dog pivotally connected to an arm cl, extending from the gear 0 and engaging with the teeth of the ratchet-wheel B. This dog is controlled or held imposition by a spring cl, which has one end secured to the arm d. A clutch-dog D" is pivotally connected to an arm (1 extending from the gear? wheel 0, and is held in engagement with the teeth of the wheel B by means of a spring The dogs D D are designed to rotate the will appear hereinafter.

E designates an operating-frame consisting of the two vertical rack-arms e e, which engage with the gear-wheels C O. The frame E has an extension E, pivoted at its lower end to a horizontal lever E which is fulcrumed on a standard 6 rising from the base of the machine. The fulcrum-point e of the lever E is placed betweenthe center and the outer end of the lever, so thatadepression of the outer end will result in a greater rise to the opposite end carrying the frame E.

To allow the frame E to move vertically in suitable guides, (not shown,) we provide an elongated opening 6? in the end of the lever E through which the pivot-pin E passes. An upstanding'bar F has its lower end pivoted to the. outer end of the lever E and a foot-plate F is rigidly attached to the upper end of this bar F. A link f is pivoted at one end to the standard e and at its opposite end to the bar F. This link serves to hold the bar F in an upright position, and by means of its pivotal connections allows a vertical movement to said bar. o The operation of the mechanism above described maybe stated as follows: When pressure is brought to bear upon the plate F by kicking or pushing with the foot or by striking the plate with a heavy mallet, the lever 5 E is operated to raise the racks e e. In this movement'the rack 6, through the agency of the gear 0, the ratchet-wheel B and the dog D, rotates the shaft A to return the dial to its normal or zero point, the dog D riding too over the teeth of the wheel B without imparting action thereto. Upon relieving the power the spring D which is secured at one end to the base of the machine and at the other end to the lower end of the extension which normally closes the opening a or is arranged between it and the disk or dial, as shown. The shutter Gis attached to a lever g, which is here shown as pivoted to the hanger a and provided at its outer or free end with a coin-receptacle g A chute:(not shown) guides a coin to this receptacle. G is a counterbalanced latch pivoted on the upper portion of the rack 6. When a coin of proper weight is inserted in the receptacle,

the lever g is rocked downward, carrying the shutter out of the line of the opening a and a lifting-pin g 'on the lever 9 comes in contact with the upper side of the free end of the latch G, turning it on its pivot until the lifting-pin passes or slides beyond the latch, when the latch, by means of its heavy or counterbalance end, resumes its normal position, with the pin 9 bearing against its under side. The coin is then discharged and astop g secured to the end of the rack e, prevents an upward movement of the free end of the latch G, so that the shutter G is held away from the opening until there is another up ward movement of the rack-frame, when the pin 9 is released and the lever allowed to rise, closing the shutter. It will be observed that the movementiof the pin g is in the arc of a circle, so that it will not engage with the latch G until a coin is inserted, as before stated.

Having described our invention, what we claim is-- 1. In a power-testing machine, the combination, with the main shaft, of a dial mounted I on said shaft, ratchet-wheels mounted on said shaft, gear-wheels loosely mounted on the shaft, clutch-connections between the gear- Wheels and adjacent ratchet-wheels, and racks engaging the gear-wheels, substantially as specified.

2. In a power-testing machine, the combination, with the main shaft and a coin-operated shutter, of a dial mounted on the shaft,

two ratchet-wheels rigidly mounted on the shaft, gear-wheels loosely mounted on the.

scribed, engaging with the rack, of a counter- 1 balanced latchp'ivoted on the rack, a shutter, i a pivoted lever extending from said shutter, a coin-receptacle on the free end of said lever, and a lifting-pin on the lever to engage the latch, substantially as specified.

5.v In a coin-operated powertesting machine,

- the combination, with dial-rotating mechanism substantially such as described, comprising a vertically-moving rack, of a shutter and a coin-receptacle having a lever, portion detachably engaging with said rack in its movement, substantially as specified.
